Letters Patent No. 91,597, dated June 22, 1869.

W FIRE-PLACE GRA'I'E.

m The Schedule referred to in these Letters Patent and part of the same.

To all whom it may concern.-

Be it known that-'LLnoroLD BERTSCHE, J r., of Allegheny City, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in FireGrates; and I that the following is a full, clear, and exact description thereof, which will enable others skilled in the artto make and use the same, referencebeing had to the accompanying drawing, forming part of this specification, in which- Figure 1 is a verticalcross-scction of my improved grate, taken through the line x-rr, fig.'2.- Figure 2 is a plan view of the same, part being broken away to show the construction.

Similar letters of reference indicate corresponding parts.

M-y invention has for its object to furnish an improved fire-grate, which shall be so constructed and do hereby declare 1 'O is the lower cross bar, upon the ends of which are formed round tenons, which pass through holes in the lowerends of the side-bars B, where they are se cured in place by pins, or other conveniently-detachable means. v a V D are the grate-bars, upon the upper ends of which are formed cross-heads, d, which enter a longitudinal groove formed in the upper bar A. and the body of which enters a transverse notch formed in the said cross-bar A.

The lower ends of the grate-bars D enter and rest in notches formed in the lower cross-bar'O, as shown in figs. '1 and 2; 1

By this construction, byturning the lower cross-bar D, the bars 0 may be new ones. Should there beoccasion, the side-bars B may be readily detached by removing the 'pin or pins by means of which they are secured in place.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, isp a The grate-bars D, constructed with cross-heads d, in combination with the upper bar A, lower bar 0,

and detachable side-bar B, said parts being constructed, 7

arranged, and operating substantially as herein shown and described, and for the purpose set forth.
